Just put a 493 stroker in my 71 dart. Had to go with a 5qt pan due to the idler arm. Wondering if the motor would run dry????? Have 1/2 inch pickup,Windage tray. Can't find a pan with the correct clearance?

I doubt if it will ever run dry.

what oil pump, what heads, what type of rpm does it see?

high volume oil pump,452 heads. rpm would be good to 7000 with the cam being used.

Nope, not enough IMO. You can overfill it by 1 qt, and run the longer filter. But IMO, you need at least 7 qts, which would be an overfilled Hemi pan. 7K and a HV pump needs a lot of oil volume.

High volume pumps won't suck a pan dry. That's an old wives tale. This has been didcussed over and over again.

at 7K, with only a 5qt sump, they very well might. That's why I asked.

Unless the oil returns are all plugged the oil will go back as fast as it gets sucked out. The oil still has to go through the same very limited escape routes between the bearings and a high volume pump doesn't make those any bigger.

I agree. And it will get backed up in the valley and around the crank at that rpm. Not to mention G forces pusing it up the back of the pan. We agree on the idea. I suppose I'm a little more cautious about applying it to every situation...lol.

There has to be a pan that will work.

SS cars, etc run big blocks in those cars.

Ok,thanks for the info. I wouldnt run it at 7k, just said it was good to that rpm. I'm sure other people have had this problem with the pan being hit by the idler. Havent found a pan that would work.

Theres a lot more to "big engines" and "small oil" than the size of the pump.

First, with a huge be stroker motor, you've got LOTS more windage, and less room to deal with it. That causes foaming problems. One reason to use a deep pan is NOT to get more oil, but to get the oil sump FURTHER from the crank

Any engine that you "tend" to run harder (more RPM, more accelleration) is going to cause oil starvation and foaming problems

I say, figure out how to get a bigger pan in there. You're not the first guy to put a "big mota" in a Mopar

I'd set the pickup ~1/8 off the bottom rather than flat like commonly recommended. High rpm/hi vol pump, I think that could end up causing starvation by being a restriction.

I use the 1970-71 stock Hemi-440-6pak oil pan in my Duster with a stroker BB,my motor is slid back one inch from the stock location based on the trans mount. I did have to trim the backside of the K member some to get the pan to clear, I used the stock 440-6pak 3/8 pick up also The motor pulls really hard to 7300+rpm and I've never had a oiling related problem yet in three + years of hard street and strip driving. I use a stock Mopar windage tray and I built the crankshaft scraper for the motor I also had the #4 cam journal grooved so the rockers would oil full time still no oiling return issues that I'm aware of, the motor has been apart several times changing parts and inspecting for the next years use there are a number of oil pans that will work in your chassis but most of the aftermarket ones are a deep sump like the Moroso and Milidons, which for a street car I don't like or use

I suck the pan dry in my Demon's 340 (TRW HV pump, stock pan, baffled and with a windage tray) if I don't run it a quart high. Only under heavy acceleration.

i imagine he watches the oil pressure gauge

Yep, that would do it.
